Hi Short answer: from the pdfbox FAQ entry ( https://pdfbox.apache.org/1.8/faq.html#threadsafe) point of view: no, generally you cannot assume thread-safety with the pdfbox library.
However, it is my personal experience that you can easily parallelize certain tasks calling pdfbox library methods using a miminal amount of care and design in the way you invoke and synchronize the threads. With regard to your issue, I'm afraid that you would need to provide more information: - What is the exact error message you get? - How exactly is your libertine_R variable defined? E.g.: a global static final PDFont? - How do you use your libertine_R variable inside the threads? - Could you share some more of your code, especially the part of the worker threads? - Which framework do you use for your multi-threaded approach?
